The chairman of the Federal Communications Commission made remarks today that indicate the agency may review complaints filed about AT&T's decision to limit the use of FaceTime video chat over its cell network, The Verge reported.

FCC Chairman Julius Genachowski said he couldn't comment on AT&T specifically, but if efforts to resolve any disputes aren't resolved and a complaint is filed, "we will exercise our responsibilities and we will act."

An FCC representative confirmed to CNET that Genachowski made the comment during a question and answer session after a speech at Vox Media's offices in Washington, D.C.

AT&T and other carriers have been struggling with the issue of increasing data use from mobile users, a problem compounded by the rise of data-gobbling video-chat applications like Apple's FaceTime.

AT&T announced in August that users on its Mobile Share plan can run FaceTime over its cellular network, but other plans still require Wi-Fi to use the video service.
